Public Involvement

Overview of the Statewide Public Involvement Process

Public participation is a critical element in developing the Regional and Statewide transportation plans. Public participation provides an opportunity for citizens to gain a fundamental understanding of the regional and statewide transportation planning process and participate in long-range transportation plan development.

If you are interested in participating in public involvement activities or having your name added to our mailing list, please e-mail Aaron Willis at and provide us your name, e-mail address and mailing address. Or contact Aaron via phone at: 303-512-4019.

Additional ongoing efforts include STAC meetings and STIP Amendments. Please click on the links to find information regarding these efforts.

Non‐Metropolitan Local Officials Consultation Process
